Abstract: Background. The purpose of this study was to estimate the value of native magnetic resonance imaging (MRI) and direct gadopentate (Gd-DTPA) magnetic resonance arthrography (MRA) in diagnosing posttraumatic pathological changes of the glenohumeral joint. Patients and methods. In 27 consecutive patients with clinicaly significant trauma in whom native MRI of the glenohumeral jointwas not diagnostically conclusive direct MRA with paramegnetic contrast agent was accomplished. Following intraarticular injection of Gd-DTPA diluted in saline (concentration 0.2 mmol/l) T1W spin echo (SE) and gradient echo (GE)images were performed. Diagnostic results of native MRI and MRA were compared. Results. MRA revealed 5 rotator cuff lesions, 7 labral lesions, 4 osteochondral injuries and a loose body which were not definitely proved by native MRI. All the pathological findings of MRA were confirmed operatively orarthroscopically. Conslusion. Direct MRA with Gd-DTPA showed to be a more sensitive technique for the demonstration of clinically significant intraarticular posttraumatic changes than noncontrast MRI.
